5000 BTU is a tiny amount of cooling - are you sure you don't mean 50,000 BTU? A 5000 BTU might give you a drop of 5 degrees C in a 6' x 8' office with no south facing windows, as long as the ceiling isn't too high. For a normal 10' square room, 12,000 BTU is a more reasonable starting point, then add more for sources of heat gain in the room.
If you've ever flown then you used complex numbers. The basic equation w=z+1/z is used to design air foils (airplane wings). While you don't actually concern yourself with these equations anymore than the thermodynamic equations that govern the running of your car's engine. Check out the related link for some interesting application of imaginary and complex numbers, though.
You cannot jump twice in Transformice, however you can jump in the middle of the air. This is called "air jumping" This can be done by leaving a platform, not by jumping off it but simply by walking off it. This allows you to jump once in the air. For everytime you have contact with an object or platform in gains you the ability to jump once.
Air, thoughts, dreams, anything intangible

A basic split air conditioner recirculates cool air in to the room.
Gas exchange
The mass of air in a room depends on how big the room is, the air pressure at the given moment, how pure the air (is it next to a coal-burning power plant?), what planet the room is on, etc.
Here's the formula: In plain English, we're changing CFM into Cubic Feet per Hour (CFH). Then we calculate the volume of the room by multiplying the room height times the width times the length. Then we simply divide the CFH by the volume of the room. Here's how a full formula works: Now, compare the air changes in the room to the required air changes for the type of room it is on the Air Changes per Hour Download accompanying this article. If it's a lunch or break room that requires seven to eight air changes per hour, you're right on target. If it's a bar that needs 15-20 air changes per hour, it's time to reconsider. Let's look at this engineering formula differently. When airflow is unknown and you need to calculate the required CFM for a room, first you look at the Air Changes per Hour Chart and identify the required air changes needed for the use of the room. Let's say it's a conference room requiring 10 air changes per hour. Next calculate the volume of the room (L x W x H). Then divide by the required air changes per hour to get required CFM. if you have any doubt pl mail me at selvapdm@gmail.com
=== === ---- Basic physics, bernoulli principal, air moving over a wing at a higher pressure than the air under the wing causes lift, (suction upwards), and is the basic principal of flight. A similar class room experiment is done with a vacuum cleaner and an egg. === ===
Heat and humidity is drawn from the area being cooled (a room, the passenger compartment of a vehicle, etc.) and is exchanged to the refrigerant. The refrigerant gets pressurized and heated even more, then it passes through the condenser. The temperature difference causes a rapid heat exchange, as the cooler air absorbs the heat from the refrigerant in a heat exchange.
air fresheners can give a fresh scent to the entire room because vapor can diffuse into air.
Most reptiles exchange gases through their lungs. The lungs of reptiles are folded so as to make enough room for gaseous exchange.
Air exchange
It has nothing to do with energy exchange, but rather, that cold air is heavier, and will "slide" right under a mass of warm air.
Air does indeed take up room. Air molecules have a mass that takes up whatever room it is confined to.
The actual air exchange takes place in the alveoli of the lungs
